McILvEIEno-E MCCANDLESS TOWNSHIP, ALLEGHENY COUNTY,PENNSYLVANIA, AssIeNoEs ro AMERICAN snEE'r AND r-IN. rLA'rE COMPANY, OFrrrrsnuneir, PENNSYLVANIA, A CORPORA- rIo'N or NEW JEEsEY 'EoLLiN -MILI.GUID Application filed April 6,1928. Serial No. 267,996.

This invention relates to rolling -mill guides, and more particularly toentering guides for strip mills and has for its object the provision of.an entering guide which is 5 divided longitudinally, and the parts ofwhich may be simultaneously adjusted toward or away from each other toaccommodate varying widths of strips or sheets;

Heretofore, guides of this class have generthat each part separated fromthe other and such parts were separately adjustable.

In the drawings- Figure 1, is a sectional Figure2 is a sectional-planthereof. Figure 3 is an entering side elevation;

Figure Lis a fragmentary sectional elevae mannenin which the guide issupported on the rest-bar and the manner in which the nuts are mountedin the guide.

Referring more'particularly to the draw the letter A designates astandard rolling mill housing of the four-high type of mill,

which consistsof a pa r of small working rolls 2 and materiall rolls 4:.j

A rest-bar member B is secured between the sides of the mill housing atthe entering side of the mill. The rest-bar B has guide-flanges largerbacking-up 5 and 6 along its respective longitudinal edges which areprovided with. longitudinally err-"- tending undercut grooves 7 and 8,respectively, to.receive locking bolts. v

A box-type entering guide C, which is split longitudinally to form rightand left-hand parts 9 and 10, issuppor'te d. on the guideflanges 5 and 6of, the'rest-harB. The guideflanges 12 which. extend inwardly and areslidably engaged on the guide-flanges 5 and 6 of the guide-bar. Lockingbolts 14 are mounted in the guide-parts 9 and 10 and have partsiiiadjusted position'on the rest bar.

' A shaft 16. is journaled in bearings 17 on the rest-bar B and extendslon itudinally of said elevation showinga guide cgnstructedin accordancewith thisinvention applied toaroll housing. bar B and is provided"rotate the shaft 22 through and 30. The shaft'22 will, in turn, rotateby the guide-parts 9 parts 9 and 10 are each provided-with guideg mentof this invention the with right and left-hand threads, respectively,and nuts 18 are mounted against rotation in the guide-parts 9 and 10 andare in threaded engagement with the opposite ends of said shaft. J v

A worm-wheel 20 is secured on the shaft 16 and is in -mesh with'a worm21 secured on a shaft 22 journaled in bearings 23 on the bar B andextending at right angles to the shaft 16. i

The rest-bar B is provided with a housing portion 2a which enclosestheworm 21 and Worm-wheel 20 so that they may besuitably lubricated.

A hearing bracket 25 is secured on the rest w'th a bearing 26 for theouter end of the shaft 22 and with bear-, ing's 27 at each end inwhich ashaft 28 is The shaft 28 is provided with a bevel gear 29 which ismeshed with abevel gear 30 on tlie shaft 22 and a hand-wheel 31 issecured on the end of the shaft 28 by which the shaft necessary toloosenthelocking bolts 14 and then to operate the hand wheel 31, whichwill rotate the shaft 28, and the shaft 28 will the gears 29 worm thethreaded shaft. 16 by means of the 21 and worm-wheel 20, and the shaft16' will i be threaded into or out of the nuts 18 carried and 10 andwill thus cause a simultaneous movement of the guideparts along therest-bar. After the guide parts have thus been simultaneously adjustedthey will be again locked in position by tightening the bolts 14.

' By providing thenovel adjusting arrange labor of adjusting reduced,the time the guides is materially minimum, the guides are alwayscentered, and more accurateadjustments are possible.

While we have shown and described one specific embodiment of ourinvention it will be understood that we do not wish to be limitedthereto, since various modifications necessary to adjust the guides isreduced toa may be made without departing from the scope thereof asdefined in the appended claims.

We claim r 1. The combination with a strip mill comrising a roll housinghaving working rolls o.urna1ed therein, of an entering guide mechanism,said entering guide mechanism com-- prising a rest-bar secured'be'tweenthe sides ofthe roll housings on the entering side thereof, a box-type'entering guide projecting forwardl into proximity to 'said rolls, saidguide being composed of right and left hand parts and being slidablymounted on said rest-bar, a shaft journaled in bearings on said rest-barand extendingtransversely v of said guide, right and left-hand threadson said bar, nuts mounted in each of said entering guide-parts andhaving threaded engagement w1th said shaft, and means for rotatmg saidshaft to cause said nuts to move said guide-parts simultaneously towardand away from each other, said means including a worm-wheel on saidshaft, a worm in mesh with said worm-wheel, a shaft and suitable gearingfor operating said worm, and a housing formed integral with'saidrest-bar and enclosing said worm and worm-wheel.

2.- The combination with a strip mill comprising a roll housing havingworking rolls v ournaled therein, of an entering guide mechanism, saidentering guide mechanism comprising a rest-bar secured between the sidesof the roll housing on the entering side there t? of, a box-typeentering guide projecting forwardly into proximity to said rolls,saidguide bein composed of right'and'left-h'and parts and eing slidablymounted on said rest-bar, a shaft j ournaled in hearings on saidrest-bar 40 and extending transversely of said guide,

right and left-hand threads on said bar, nuts mounted in each of said"guide-parts and having threaded engagement with said shaft, means forrotating said shaft to cause said 1 nuts to simultaneously move saidentering guide-parts toward and away from each other, said meanscomprising a worm-wheel on, said shaft, a second shaft journaled inhearings on said rest-bar and extending at right angles to said firstnamed shaft, a worm on said' second named shaft and meshed with saidworm-wheel, a third shaft extending transversely of said housing andjournaled in bearing brackets carried by said rest-bar, gearingconnecting said second and third named shafts, and a hand-wheel on saidthird shaft whereby said shaftsmay be rotated to adi'ust saidguide-parts.

, n testimony whereof, we have hereunto set our hands; i.
